Because you have done something wrong?

Did you expect a better answer? You aren't giving any specific details in your question.

try to be more precise:

import javax.swing.*;

public class FormA extends JFrame{

/**

* @param args

*/

public static void main(String[] args) {

JPanel jp = new JPanel();

JButton jb = new JButton("Open");

jp.add(jb);

// TODO Auto-generated method stub

}

}

your code is good, but you do not decide what you will do with your panel.

add this statement to your code:

getContentPane().add(jp, BorderLayout.CENTER);

ofcourse after:

JPanel jp = new JPanel();

do not forget to add:

import java.awt.BorderLayout;

I hope this will be helpfull.
